glitened, to 13o lien ti Uien using the device on a music stan-d` an attachment is preferably usedy to enable the latches to be operated by the foot, es-

pecially when the playerl cannot conveniently operate thelatches by hand. This attachment includes a supplementary stand-y ard 48 comprising the upper bar orsection' 49 having a clamp-50 at its upperfend to engage the lower righthandportion-of the frame l0, and a lower bar or section 5l having the diverging feet 52 to rest on the floor. The adjacent terminals of the bars 49 and 5l overlap one another and have series of apertures to register in the different adjustments of the standard 48 to correspond with the adjustment of the standard 40. A U-bolt 54 is insertible through registering apertures 53, and an elongated washer is engageable on the terminals of the bolt, and the parts clamped together by nuts 56 or other retaining elements engaged on the terminals of the bolt.y

Upper and lower horizontal guide bars 57 are attached to the bars 49 lland 5l of the standard 48, and have clamps 58 of any suitable kind to embrace the standard 40. Actuating members 59 are slidable up- K wardly and downwardly in the bars 57,

there being one of said members for each latch of the leaf-turning device. Each of the members 59 includes the upper and lower bars or section 60 and 6l having their adjacent terminals overlapping, similar to the sections or bars of the standard 48. The bars 60 have rearwardly extending portions at their upper ends extending over and resting on the linger pieces 39 for the de- -aehable engagement of the latches and bars, and the bars 61 are provided at their lower ends with foot pieces 63 to be readily depressed in succession by the foot of the player. The bars 60 and 61 of the members 59 are adjustably connected similar to the bars or sections of the standard 48. Thus, the overlapping terminals of the bars 60 and 6l have the series of apertures 64 to register for the insertion of U-bolts 65 on which the elongated washers 66 are engaged and also the nuts 67 or retaining elements. The members 59 are thus adjustable longitudinally to different lengths according to the adjustment of the standards 4() and 48 to spacel the foot pieces or pedals (58 a convenient distance above the floor, and, if desired, a block 68 `can be placed on the floor under said foot pieces to limit the depression thereof.

lli/'hen the foot attachment is thus applied, the latches' can be released in succession by the vfoot of the player, and the Vdepression of the foot pieces 63 will pull ythe members 5f) downwardly, so that the portions (52 thereof will pull the latches down also. However, if desired, rthe latches can still be depressed by hand.

It `is preferable to extend the bills 27 of thel lower hooks 27 of the wires 28, so that saidfhooks can be engaged over the lower eegesof the leaves, to prevent'the leaves from:stickingv or adhering together when turning the leaves, and thereby holding the leaves against the respective wires 28. This will`1avoid the accidentaly turning of one leaf-with the other.

Having thus described the invention, what is claimed as new is l. A music leaf turner comprising rock shafts having arms to be disposed above and below the leaves, wires to extend across the leaves having coupling members at their ends to engage said arms, and means for swinging said arms.

2. A music leaf turner comprising a frame, a set of rock shafts carried by the frame and having upper and lower arms to be disposed above and below a book supported by the frame, wires to extend across the 'leaves of the book, hooks at the ends of said wires to engage said arms and means for swinging said arms.

3. A music leaf turner comprising a frame for supporting a book, spring-pressed clamps hinged to the frame to overlap and hold the covers of the book and arranged to swing away from the frame, manually operable members extending behind the clamps for swinging said clamps open, and leafturning members carried by the frame.

4. A music leaf turner comprising a frame for supporting a book, leaf-turning members carried by the frame for swinging movement at the front of the frame, retractile springs carried by the frame at the rear thereof, said members having loops, liexible elements connected to said loops and springs, the frame having an opening through which said iiexible elements extend and into which the loops are moved when said members are swung by the springs, and latches for holding said members when they are swung to pull the flexible elements and stretch the springs.

5. A music leaf turner comprising a frame for supporting a book, spring-actuated leafturning members carried by the frame, latches carried by the frame for holding said members and operable by the fingers for releasing said numbers in succession for turning movement, means for clamping the frame on a music sta-nd, and means attachable to such stand and including foot-operable members to detachably connect with said latches.

6. A music leaf turnerl comprisinga frame for supporting a book, spring-actuated leafturning members carried by the frame,

@ i ,assess latches carried by the frame for holding said members and releasing them in suc cession for turning movement, foot-operable members detachably engageable with said atehe and means :for guiding said footoperabie members and retaining same inoperative relation with the frame.

T. .A mu, ic leaf turner comprising`- a frame Ator su porting a book, spring-actuated leafturuirim members carried by the frame, latches carried by the frame for holdingn said members and releasing` them for turning movement iii succession, a standard having means for attachment te said frame, guiding means attached to said standard and having means for attachment to a music stand, and

members slidable in said guiding means ha-V- mg portions at their upper ends to engage said latches and having foot pieces at their lower ends.
